Not my experience with CA. I own an OD2 and OD3r, and the clean sounds are anything BUT thin and plinky. Big and brassy is more my experience, which is over a period of years (I've owned the OD2, which was originally Eric Johnson's, for nearly 10 years now) and plenty of gigs. Lots of hours in on both amps. The only Dumble experience I have (well, discounting being in the studio last week with Robben and his, or being in a small venue sitting right in front of Sonny Landreth's, i.e., only considering actually playing the amp myself with one of my guitars) is with Kimock's 50-watter, his main one. My K&M "Kimock" amp is pretty close to that overall -- note that mine isn't stock, it's been modded a few times (by Bill K) with the same tweaks Kimock had done to his own amp -- and relative to the CA amps nothing "destroys" anything. Just different flavors of good. Overall I think the OD2 is bigger and bolder, with more headroom than the K&M, or Kimock's Dumble for that matter. Maybe not quite as sweet though. Just kinda depends on the application as to which I prefer.
